I have the worst clay soil on this planet. I was digging down deep in a area to ammend the soil when I saw just how bad it is. It's perfect for a pottery class. When I got down about 8 inches, the color went from medium brown to a lighter tan! I was disgusted.
I am planning to start digging the stuff up in my raised beds, tilling and ammending it with humus, compost and perlite. Does this sound like overkill? Is compost and humus too much?
